TIRE RIM 0F MOTOR .AND `LIKE VEHICLES Application led September 8, 1927, Serial No.

This invention relates tothe usual types of removable tire rims used principally in connection with the wheels of motor vehicles, to hold the pneumatic tires thereof and which placed on and removed from the wheel.

The obj ect of the invention is to provide a construction of rim that will allow for the easy removal and replacement of a tire thereon and that will hold the tire securely in its position on the wheell when the rim is secured thereon in any of the usual ways or variations thereof.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the wheel rim. f

Figure 2 is an end elevation thereof, a portion beingV in section.

Figure 3 is an `enlarged cross sectional elevation taken through one of the joints, and showing one form of the invention.

Figure 4 is a longitudinal section on the line 4 4 of Figure 3.

Figure 5 is a similar view to Figure 3 but showing an alternative 'form of the inl vention.

Figure 6 is a longitudinal section on the line 6-6 of Figure In this invention the rim is made in two circumferential parts or sections A and B which butt together to form the whole channel shape required in these rims. On one section B at approved distances apartfaround its .outer periphery are lugs C which'may be attached or formed integrally with this section and Vwhich extend transversely and overlap the periphery of the other section A.

In some vinstances'these ylugs may be arranged only upon the outer periphery of the part B so that they overlap the outer periphery of the part A, as in Figures 3 and 4. In other instances, in order*I to increase the strength, the lugs may be arranged in pairs on both faces of the' part B'so that the part A then passes in between them, as in Figures l, 5 and `6. Each lug near its end is made with an aperturel 0 therein and this coincides with a similar aperture a made through the part of the rim overlapped there- 218,335, and in New Zealand April 265,192?.

by, and with the aperture in the other lug; ofthe pair when the` lugs are arranged inl` In connection with each such lugY or each `pair of lugs,'there is attached to the inner periphery ofthe part B, a springV tongue VD which is curved to lie against the arcr surface of the inner periphery of the rimMand-is attached to it at one end byv a rivet d? which causes it to spring normally outward into close Contact with the said surface. This rivet also forms a pivot upon which the tongue may be swung laterally at its free end'. The tongue in some instances may be pivoted on the part A.

The said tongue, at itsfree end, has a pin E affixed to its outer face and the tongue is so positioned that this pin is adapted to pass out through the aperture a of the part A by reason of the normal springy tension of the tongue. The pin is made long enough to pass into the aperture c of the lug C or through both lugs when such lug or lugs has or have been passed across the part A in the assembly of the tworim parts together. It therefore serves to lock the two parts in the assembled condition, and as it also ex-y tends diagonally across both parts, it serves as an additional strut to hold the two parts together. These means being disposed at av number of points around the circumference of the rim, an effectual working jointing of f the two parts is obtained.

When the parts A and B are to be disv pins to Y 100 In some instances the relative positions of the'lugs and spring tongues may be varied and other alterations in details may he made i Ywithout departing from the general features of the invention.
